Tiffany's partner and one of its main suppliers of diamonds is Israel's Steinmetz Diamonds Group. The Steinmetz Diamond Group through the Steinmetz Foundation funds and supports the notorious Givati Brigade of the Israeli army which stands accused of war crimes and possible crimes against humanity by the United Nations Human Rights Council.

The Givati Brigade is responsible for the massacre of the Samouni family in Gaza during Operation Cast Lead. On 4th January 2009 the Givati Brigade rounded up 100 members of the Samouni family and ordered them into the house of Wa'el Samouni. The house was then bombed, and rescue services were prevented from approaching for four days, with ambulances being fired on. When rescue workers were finally allowed access, they found buried beneath the rubble, traumatised children besides the corpses of their parents and siblings. The Givati had massacred 29 family members and in case anyone mistook their intent they left a message on one of the remaining walls of the house, daubed in Hebrew it read "The only good Arab is a dead Arab".

The Foundationís website boasted of "adopting" a unit of the Givati brigade, of "fostering close relationships with the commanders and their soldiers", of "buying equipment " for them specifically during Operation Cast Lead, that is, during their slaughter of the Samouni family.

All references were however deleted from their website once it came to public attention - but not before we took copies of their website:

"For most journalists, whether they realize it or not, are groomed to be tribunes of an ideology that regards itself as non-ideological, that presents itself as the natural center, the very fulcrum of modern life. This may very well be the most powerful and dangerous ideology we have ever known because it is open-ended. This is liberalism."
